The song of the summer is here with "All In My Head(Flex)" by Fifth Harmony! Not only does this have the island vibes we need but it makes you want to dance around a pool with a delicious cocktail (or ten). These girls have never looked better and are CLIMBING their way to the top. Bring that sass girls cus I know I am, every. damn. time. I. play. this.... and I have played it over 100 times already. (Also loving that hot man candy, sure to give you a sweet tooth) #Flex
